Oval gear flowmeter scale installation and matters needing attention

Abstract: the oval gear flowmeter scale installation and matters needing attention of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Oval gear flowmeter is used to measure the liquid flow precision instrument, accumulated direct reading instrument, is the sum of measuring liquid flows through the pipe flow displacement meter. Products choose mechanical display meter and electronic display meter two counts, display table. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the oval gear flowmeter scale installation and matters needing attention for details. Oval gear flowmeter is used to measure the liquid flow precision instrument, accumulated direct reading instrument, is the sum of measuring liquid flows through the pipe flow displacement meter. Product choose mechanical display meter and electronic display meter two counts, display header has accumulated flow and transient flow and back to zero, which can realize the scene display and remote control. Oval gear flowmeter installation 1, before installation should be thoroughly clean the pipe, and in front of the flowmeter filter installation, in order to prevent debris into the meter. When measured liquid containing gas, should install air separator. 2, should pay attention to must take meter oval gear shaft United States level, namely the dial and perpendicular to the plane. Flow adjustment and start, shut off the valve should be installed in the import and export of flow meters respectively. 3, flowmeter shell on the arrow pointing in the direction of piping shall be installed with the liquid flow in the same direction. 4, the continuous flow of pipeline, the installation of flowmeter horizontal line should be equipped with a bypass valve, in order to regular cleaning and maintenance. On the vertical pipe flow meter, shall be installed in the bypass duct to prevent debris into the instrument. 5, under the condition of correct installation of the flow meter, for ease of reading, can according to the need to counter rotating 180 & deg; Or 90 & deg; Oval gear flowmeter note 1, instrument installation shall be made in the direction of the arrow direction as shown on instrument housing and liquid flow in the same direction, the installation position should be paid attention to easy reading. 2, instrument installation as far as possible in normal situation, do not install in place of harmful gases and strong heat radiation, prevent the meter counter parts from damage. 3, instrument of the elliptical gear shaft installed into a horizontal position as much as possible, namely the readout panel shall be installed in vertical position ( Counter positive parallel to the ground) , in order to reduce friction between the elliptical gear and shell, the lower parts of wear and tear. Due to the installation position is different, in order to facilitate reading, can be counters ( Header) Rotate it 90 & deg; Or 180 & deg; 。 4, instrument before installation, pipeline must be thoroughly cleaned and in the whole pipeline system, without strict filtering device, filters should be installed in front of the instrument, to prevent impurities into the table. 5, meter should be installed at the outlet of the pump, flow control valve should be installed on the downstream side of the instrument. When used to open the upstream shutoff valve and then slowly open the downstream flow control valve or valve. It is forbidden to suddenly open or closed. 6, instrument when use, should make the inflow table filled with liquid. Within the measured liquid should not be mixed with gas, or a mixture of gas and liquid volume is measured, the measurement, the liquid mixed with gas, within the instrument must be installed upstream gas separator. 7, of the pipeline flow should not increase or decrease sharply, should avoid pipeline hydraulic shock and vibration, pressure phenomenon such as volatility, otherwise will affect the normal work of the instrument. 8, when the flow rate is in excess of that specified maximum flow, oval gear wear increases with the rotating speed increases, and the pressure loss has increased dramatically, should avoid to use. Below the minimum flow, is still can measure, but the error increase. Meter starting flow is about 2% of the maximum flow, work flow for - 70% of the maximum flow 80%. 9, because when measuring high viscosity liquid, usually in order to reduce the viscosity of liquid heating, then the flow in the pipe ( With both insulation clip model flow meter) 。 After the instrument downtime, instrument inside filled with liquid by cooling and become sticky, such as to enable the again, must be used on the outside of the table body heat, steam or other methods to reduce the viscosity of the liquid, the liquid viscosity reduced in the instrument to use. Or mucus will bite transmission parts, instrument damage. 10, measured liquid temperature should not be higher than the specified value, otherwise, the instrument can not work normally, even stuck, counter parts easily damaged at high temperature. The liquid temperature change can cause additional error viscosity influence. 11, each instrument factory, all use 0 # diesel oil at room temperature calibration, at room temperature, the viscosity of the oil is about 3 mpa. s。 If user use this large difference with the liquid viscosity, or need to reset the gear ratio flow coefficient. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

The increasing consumption demand in key segments such as insertion ultrasonic flow meter, endress hauser coriolis mass flow meter and low flow turbine flow meter have been driving the sales of and its derivatives worldwide.

Growing revenue is a common goal for many businesses. We want to be sure Sincerity include leaders from the marketing, sales and production departments to help make certain that the goals we choose are appropriate and have strong support.

In conjunction with retraining and upskilling efforts, Beijing Sincerity Automatic Equipment Co., Ltd’s workers should focus on growing unique human skills that high-tech machines are unable to replicate, such as strategic and abstract thinking, complex communications, creativity and leadership competencies.

have three basic components.

But we do think that reckoning with supply chains of mass flow meter is a really important step. Even super simple switches in material, or sourcing, or shipping, or worker benefits seems like good place to start.
